  • The data demonstrated that inhibition of HuR destabilized SNAI1 mRNA, and subsequently reduced Snail protein levels, resulting in the EMT and CSCs inhibition in pancreatic cancer cells. (ku.edu)
  • In the present study, we revealed that microRNA-30 (miR-30) members, especially miR-30b, were remarkably downregulated in triple-positive (CD24 + , CD44 + , EpCAM + ) pancreatic cancer stem cells (PCSCs). (jcancer.org)
  • Our laboratory has recently discovered a novel epithelial stem cell compartment, Pancreatic Duct Glands (PDG). (nebraska.edu)
  • We hypothesized that the acquisition of cancer stem cells (CSC), a subpopulation that drive tumor initiation and progression, may contribute to CNT carcinogenesis. (cdc.gov)
  • During inflammation, reactive oxygen species (ROS) and reactive nitrogen species (RNS) are generated from inflammatory cells and are considered to play key roles in carcinogenesis [ 3 ]. (hindawi.com)
  • Recently, evidence has accumulated showing that stem cells are involved in inflammation-related carcinogenesis. (hindawi.com)
  • It often has multiple types of cells mirroring their counterpart in the body along with constituents of native extracellular matrix (ECM) and is typically miniature or micro-scale in size. (stemcell.com)
  • TGFβ1 expression in CRC cells, and its level in the cell medium and extracellular matrix was increased in primary tumour CRCs overexpressing TG2 and could regulate TG2 expression and EMT by both canonical (RKO) and non-canonical (RKO and SW480) signalling. (oncotarget.com)
  • We found that epithelial reprogramming and extracellular matrix (ECM) production persisted after removal of the fibrosis cocktail. (lu.se)
  • Human colon cancer cell lines (CRCs) RKO, SW480 and SW620 were investigated for TG2 involvement in tumour advancement and aggression. (oncotarget.com)
  • We now seek to explore how different signals and cell-cell interactions modulate this and other repair mechanisms, and how these go awry in disease. (findapostdoc.com)
  • Within the cancer population of the tumors there are cancer stem cells (CSC) that are tumorigenic cells and are biologically distinct from other subpopulations They have two defining features: their long-term ability to self-renew and their capacity to differentiate into progeny that is non-tumorigenic but still contributes to the growth of the tumor.
